What it does
The Voltage Sensor Module for Arduino & Raspberry Pi | 0-25V DC Voltage Detection uses a precision voltage divider to safely measure DC voltages up to 25V using a microcontroller’s analog input. Ideal for battery monitoring and power management applications.
Key features
- Measures 0-25V DC safely with microcontroller
- Precision voltage divider with stable resistor values
- Safe for 5V microcontrollers – output scaled to ADC range
- 5% tolerance resistors for reasonable accuracy
- Compact module with standard header pins
- Easy to use with single analog pin connection
- Two-pin input for direct voltage measurement
Good to know
- Do NOT exceed 25V input – will damage module and microcontroller
- For accurate readings, calibrate with known voltage source
- Resistor tolerance (5%) affects accuracy – calibrate for best results
- For higher voltages, use external voltage divider with appropriate resistors
- Consider using dedicated INA219 for current + voltage monitoring
